If these causes are ruled out, the probable cause is a misadjusted gas valve regulator. Refer to Section 1.4, Checking the Burner Manifold Gas Pressure, for the gas valve adjustment procedure.

1.7.3 Improper Temperature Control

Temperature control, including the melt cycle, is a function of several interrelated components, each of which must operate correctly. The principle component is the temperature probe. Other components include the interface board, the controller, and the ignition module.

Improper temperature control problems can be categorized into melt cycle problems and failure to control at setpoint problems.

MELT CYCLE PROBLEMS

In fryers equipped with analog controls, the melt cycle must be initiated by pressing the melt cycle switch. With all other controllers, initiation of the melt cycle is automatic. Problems may originate from the controller, the temperature probe, or a malfunctioning heat relay on the interface board.

FAILURE TO CONTROL AT SETPOINT

Problems in this category may be caused by the temperature probe, the interface board, or the controller.

1.7.4 Computer Malfunctions

SENSITIVITY OR “STRETCH AND SHRINK TIME.”

Sensitivity – “stretch time” – is a programmable feature, patented by Frymaster, which increases or decreases the cook time countdown based on variations in the oil temperature from the set point.

The sensitivity for each product button has ten settings (0 through 9). A sensitivity setting of zero will disable the feature (no change in cooking time), while a nine will provide the highest sensitivity or most change. The correct sensitivity for any product is based on the product, its density, the set point temperature, and the customer’s own requirements. A chart is provided in the Frymaster Fryer Controllers User’s Manual included with your fryer to assist you in setting sensitivity.

RECOVERY TIME

Recovery time – is a method of measuring a fryer’s performance. It is the time required for the fryer to increase the oil temperature from 250ºF to 300ºF (121ºC to 149ºC). This range is used as a standard since ambient kitchen temperatures can effect the test if lower ranges are used.

The Computer Magic III.5 performs the recovery test each time the fryer warms up. An operator can view the results of the test any time the fryer is above the 300ºF (149ºC) point by pressing the button and entering the code 1652. The test results will be displayed in the computer’s LED panel in minutes and seconds. The maximum acceptable recovery time for Pro H55-Series gas fryers is two minutes and twenty-five seconds.
